Description

Technical Field

[0001] The invention relates to the technical field of pest trapping, and in particular to a fall armyworm trapping device based on solar energy. Background Art

[0002] The beet armyworm, commonly known as the cabbage brown armyworm, belongs to the order Lepidoptera and the family Noctuidae. It is a omnivorous pest that is distributed worldwide and occurs intermittently and mainly harms vegetables. It is harmful to vegetables such as green onions, kale, Chinese cabbage, celery, cauliflower, carrots, asparagus, water spinach, amaranth, peppers, cowpeas, cauliflower, eggplant, kale, tomatoes, Chinese cabbage, Chinese cabbage, broccoli, spinach, and radishes. Therefore, traps are often installed at vegetable planting sites to capture the armyworm.

[0003] Trapping devices mostly use sex attractants for trapping, however, the sex attractants cannot be volatilized over a large area to attract the fall armyworms, so multiple trapping devices need to be installed, which is expensive.

[0004] In order to solve the above problems, a Chinese utility model patent with publication number CN215531047U discloses a fall armyworm trapping device, including an insect collecting tank, a bottom cover is provided on the bottom surface of the insect collecting tank, a support column is fixedly provided on the top surface of the insect collecting tank, a blocking cover is provided between the multiple support columns, a top column is provided on the bottom surface of the blocking cover, a hanging screw is screwed on the top surface of the top column, a volatilization cover is fixedly provided on the bottom surface of the top column, a silent motor is embedded on the bottom surface of the volatilization cover, a fan blade is fixedly provided on the output end of the silent motor, a clamping ring is fixedly provided on the bottom surface of the volatilization cover, a volatilization box is sleeved on the outside of the clamping ring, a hollow medicine tube is provided at the lower end of the volatilization box, and a sealing cover is hinged on the top surface of the hollow medicine tube.
